Answer:

8 3/4 degrees

Step-by-step explanation:

In 1 hour, the temperature drops 3 1/2 degrees.

In 2 1/2 hours, the temperature drops 2 1/2 times 3 1/2 degrees.

We need to multiply 2 1/2 by 3 1/2.

2 1/2 * 3 1/2 =

Change both mixed numerals into fractions.

= (2 + 1/2) * (3 + 1/2)

= (4/2 + 1/2) * (6/2 + 1/2)

= 5/2 * 7/2

= 35/4

= 8 3/4

Answer: The temperature change in 2 1/2 hours was 8 3/4 degrees.

Multiply the change per hour by the number of hours:

3.5 degrees per hour x 2.5 hours = 8.75

Since the temperature dropped, the change would be a negative value.

The change was -8.75 ( -8 3/4) degrees.

Pie

Answer:

5a^​4​​+a^​2​​b−6b​^2​​

Step-by-step explanation:

1. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.

5a^4+6a^2b−5ba^2−6b^2

2. Collect like terms.

5a^4+(6a^2b−5a^2b)−6b^2

3. Simplify.

5a^4+a^2b−6b^2

Given: AC bisects angle BCD , Angle ABC is congruent to angle ADC prove AB is congruent to AD. Help immediately
weeeeeb [17]

<em>AC bisects ∠BAD, => ∠BAC=∠CAD ..... (1)</em>

<em>thus in ΔABC and ΔADC,    ∠ABC=∠ADC (given), </em>

<em>                                       ∠BAC=∠CAD      [from (1)],</em>

<em>AC (opposite side side of ∠ABC) = AC (opposite side side of ∠ADC), the common side between ΔABC and ΔADC</em>

<em>Hence,      by AAS axiom, ΔABC ≅ ΔADC,</em>

<em>Therefore,  BC (opposite side side of ∠BAC) = DC (opposite side side of ∠CAD),  since (1)</em>

<em />

Hence, BC=DC proved.
